    My battery shows fully charged. I unplug the ac cord and after a few seconds I get "battery critical". I have tried different batteries. I think something is wrong with the internal charger circut. Has anyone fixed this? HP sent it back as not-repairable.

Battery may be faulty, perhaps you can swap with another user to rule this out. Do the battery charge level lights on the back of the battery show a full charge? (Press the rounded square button on the back of the battery itself and note whether the 3 green leds light up or not) Has the battery been calibrated? (You will need the "toaster" style or the DT533A charger to do this). I assume that your battery is secure and properly seated, but try taping it down from the back side just to be sure it is snug. Don't use duct tape, just regular scotch style tape or blue masking tape. Also try laying on your back to hold the unit upside down and power it up. Check the small metal fins that mesh with the battery. They are right above the right side of the windows cert of auth sticker when turned as you would to read it. They are NOT all the same length, do not push or pull them, but if one is bent you may try to straighten it VERY carefully with very small tools.
What happens if you unplug while up and running?
How does the power jack feel when you insert or remove it? any looseness may indicate your trouble. A good tech can repair your trouble. Are you sure that you are not under warranty? HP still sells extended warranty for these machines. My original warranty expired in Sept and I bought extended warranty for another year. I'm in central MO if you are close by at all I would meet up and swap a batt for a minute for you. Also, you may get a lil more usability with a car cord if the problem cannot be resolved at all.
Best of luck! I love my tc1100 and the older brother tc1000 as well. I have several of each.

I turn my tablet on then it switches it self off


Sounds like it does not have enough battery power to stay on. If you have not tried to charge it, you should try that first. If you have, it sounds like it is not getting charged or not holding a charge. Could be bad AC power source, bad charger, bad charger connection or bad battery. Take steps to confirm that each of these are good. If all of these are good, sometimes the tablet can become so discharged that it will not allow itself to charge. When they are in that state, sometimes you can trick them into charging again by repeatedly disconnecting and reconnecting the charger as follows: With charger plugged in to AC power source, connect the charger to the tablet. Pay attention to the screen or LED or whatever indicator your tablet has to let you know it is charging. You may see it momentarily indicate charging, or maybe not at all. Then unplug the charger from the tablet then immediately plug it back in and pay attention for the charge indication again. You may have to do this a bunch of times (like 20) until you see the indication that it is charging. When you do get the indication, stop unplugging and re-plugging and let the tablet charge for 24 hours (to a full charge). This trick doesn't always work. Sometimes the battery or charging circuit or an internal connection is bad and no amount of unplugging/re-plugging will fix a hardware problem.

Why does innotab charging light blink when charging and will not charge?


the charge imdicator is suppose to blink when you plug the toy to the wall adaptor. if it doesnt blink then there's something wrong with either the adaptor, the adaptor port on the toy or the rechargeable power packs. now i said that the light is suppose to blink. but the frequency of the blinks shouldnt be fast. if that's the case clean the compartments and re-insert the batteries. if you are still having problems try the ff T/S:

1)remove the power packs, plug the toy to adaptor and turn it on. if it turns on that means your adaptor is working.
2)remove the adaptor and try using just the power packs.
3)try using 4aa batteries.

if the toy turns on with only one of the power sources stated above you better call vtech hotline.

Kindle won't turn non


Try these:
Reset the Kindle
Hold down the power button, or hold the power slider to the right, for at least 20 seconds. Then release the power button or switch, and push it again to turn on the device. If that doesn't work, hold the power button or slider for up to a minute, then release it and try to turn on the device.

Is there a power issue?
When you plug your charger into the Kindle, the LED should turn yellow if the device is charging and green when the device is fully charged. If the light doesn't turn on at all, it definitely signals some kind of power issue. Replace the charging cord if possible.

The Kindle uses a micro-USB connector, the same as most mobile phones. Try changing the cord or if that doesn't help, try another power source - a different charger, or connect it to a USB port on your computer. Finally, gently wriggle the adapter where it enters the Kindle. If the charging port has come loose, this movement may cause the port to realign and the LED to illuminate.

Tabeo tablet battery not charging will work if plugged in


Hi! Hope this may serve as a hint. When power problem dooms to any electronic device needing battery operation we sometimes least assume that the battery life is near to its end. I mean its charging life has come to end. However, you can sometimes recycle it's life cycle by discharging fully and recharging fully without using it. Battery utility softwares can help monitor its life but cannot revive at all. Charging also using fast charger and or slow charger can help reactivate the battery cells. I personally experience, a gadget of mine its charging life is almost come to end and when I accidentally plug it on my laptop with 3.0 USB offline charging capability it somehow raise its life but not as good as it is. If the above doesn't work at all, it's time to change the battery pack. Goodluck!

My amazon kindle screen is frozen on the right hand upper corner. The rest of the screen is still fine and works but that corner is frozen.


Make sure that the kindle is fully charged. Plug your kindle into the wall charger, a yellow light will light up. When the yellow light turns green, your kindle is fully charged. Then try turning on your device. If the device still does not turn on, hold the power switch for 15 seconds, this will reboot the device.

also check the compaQ menu that is the hardware toggle to turn wireless on and off. there is no function keys like most laptops.

near where the power button is there is a button labeled Q. which will bring up a settings menu like an on scree display and that is where you toggle wireless hardware support on or off

Battery problems Tc 1100


When the Batt is inserted and you are on AC power do you have a lit charge light? It's the one in the center of the three at the lower right when you are in landscape mode.
If your batt is at "end of mission" (**** up) then it's ability to hold and take a charge may be very limited. Calibrating the batt might help. You will need the toaster style charger.
If this is the issue, then the charge light may only stay on for a few seconds at a time when you first attach AC power, so be watching.
I could recommend a new batt (e-bay) if thats your only trouble. Nothing lasts forever. I'm in Missouri and will calibrate your batt if you want to mark it and ship it. Let me know.
